Added support for vendor specific meta data in LLL conn object. This
enables vendors to add state data to connection, for supporting
specialized BLE slave features.

This is a squash merge of commits introducing the new split
Upper Link Layer and Lower Link Layer architecture of the
Bluetooth Low Energy controller.
This introduces a new, improved Link Layer based on the
concept of split responsibilities; The Upper Link Layer
(ULL) is in charge of control procedures, inter-event
scheduling and overall role management. The code for the
ULL is shared among all hardware implementations. The
Lower Link Layer (LLL) is responsible for the intra-event
scheduling and vendor specific radio hardware access.
The communication between ULL and LLL is achieved through
a set of FIFOs that contain both control and data packets.

Preparation to introduce the Upper Link Layer (ULL) and
Lower Link Layer (LLL) split architecture.
- Move SoC dependent HAL to vendor specific folder.
- Preparation to split data structures into ULL and LLL
types.
- Added more role and state conditional compilations.
- Added some work-in-progress implementation of advertising
extensions, will be used as inspiration in the new split
architecture work.
